Title: Fix the build with the newer versions of libdwarf

This fixes an error with inconsistent types being used for the 'name'
parameter when registering a libdwarf callback against newer versions
of libdwarf (versions where the 'name' parameter is a const char*).

I verified that this compiles with the latest version of libdwarf.
